Bulk Image Downloader from Page

WHAT IT DOES This tool allows you to scan any webpage for images and bulk download or export them. It detects images from tags, elements, and optionally CSS background images, extracts their source URLs with resolution information, and displays them in a scrollable grid with thumbnails, dimensions, and file names. You can filter images by minimum width and height to avoid downloading tiny icons or placeholder images. Once scanned, you can select which images to keep, then open them all in new tabs for individual download, copy their URLs to the clipboard as a list, or export them as HTML image tags for use in other projects. This is useful for designers collecting references, researchers archiving visual data, or anyone who needs to quickly grab multiple images from a page. WHERE IT RUNS The script runs on any website, making it truly universal. It does not require a separate extension popup, background process, or external server. Everything happens within the page context, interacting with the page's DOM and CSSOM. It works on any webpage with image content. HOW TO USE 1. Navigate to any webpage containing images you want to download. 2. Open the BotGentz panel. 3. Optionally configure settings: - Toggle "Include background/CSS images" to detect background images from CSS. - Set minimum width and height filters to skip small images. 4. Click "Scan Page for Images" to start. 5. The script will scan the page and display a grid of found images with thumbnails, dimensions, and file names. 6. Select or deselect images using the checkboxes on each thumbnail. 7. Use the action buttons: - "Open Selected in New Tabs" to open each image in a new tab for downloading. - "Copy URLs to Clipboard" to copy all selected image URLs as a text list. - "Export as HTML (image tags)" to copy selected images as HTML tags. - "Deselect All" or "Select All" to quickly change selections. TECHNICAL MECHANISM Unlike browser extensions that rely on the downloads API, this script operates entirely on the public DOM and CSSOM. It extracts images by scanning for tags and reading their src attributes, parsing elements and their children for srcset and src attributes, and querying computed styles for background-image CSS properties. For each discovered URL, it attempts to load the image and measure its natural dimensions to provide resolution information. The script filters images based on user-defined minimum dimensions. For the grid view, it creates thumbnail previews using the actual image URLs with object-fit: contain to maintain aspect ratios. The download mechanism uses GM_openInTab to open each image URL in a new tab, which triggers the browser's native download behavior — this is the only reliable way to download files without chrome.downloads API. All actions respect the concurrency and rate limiting rules by spacing out tab openings. THE PANEL The tool appears as a draggable, resizable panel on the side of your screen. You can drag it to any position by clicking and holding the header, resize it by dragging the bottom-right corner, and collapse it to a small bubble when not in use. Press the Escape key to close the panel. The panel remembers its position and size per domain so it stays where you left it on your next visit. PLEASE NOTE This script requires the free BotGentz extension to run. It does not store any personal data — all image scanning happens locally and no data is sent to any external server. The script uses GM_openInTab to open image URLs in new tabs; this is not a true "download" but the most reliable way to trigger downloads without chrome.downloads API. Opening many tabs at once may be slow; consider using "Copy URLs to Clipboard" with an external download manager for large batches.
